Unroot and Unbrick LG G Pad V410 AT&T Tablet back to stock

Again, my curious mind had to fiddle with another Android device causing a hard brick. After seeing here on the AT&T website that Lollipop was out for the LG G pad v410, figured could easily bring the tablet back to stock using this firmware found on XDA. Very bad move, after flashing the firmware using TWRP for the LG-v410, went into settings on the tablet, and did a software update. This caused the tablet to reboot back into TWRP recovery. Next going back to XDA, where I originally downloaded the stock zip file, flashed the stock recovery for the LG-v410. Whoops, now the tablet was, as they call it, hard bricked, now the tablet was stuck on a boot loop showing only the LG Logo.

Anyways, found the LG mobile update tool, the online one did not seem to want to work, so I came across the LG Flash Tool 2014. Only problem was, could only find firmware for newer or older models. Forums and other blogs will say that you can flash the V40010c.kdz, this may work if you did not totally brick your tablet and can still get into recovery, although, if you did what I had done, the drivers are not going to correctly install while in download mode. They may while in TWRP recovery, since you can enable MTP in TWRP recovery.

After much searching, did finally find the KDZ file for the AT&T LG-v410, if you already know what to do, you can grab it right here:

Now that you have everything you need, follow this link and unbrick or simply bring your LG G Pad 7.0 back to factory stock! The directions are for the LG G2, but the same procedure works for the LG G Pad v410.

Yes. Same Thing happened to me. Boot into the so called "factory reset mode".1) Power off2) Hold Down Volume Down3) Press and hold power while still holding volume down.4) Wait for LG screen.5) While still holding volume down, release and immediately repress and hold down power.6) Go through on screen steps to reset device.

It will take a long time to boot, but when it does it will go through the regular initial device setup.
